| File:Ambox important.svg | Administrators: Please do not delete this category as empty! This category may be empty occasionally or even most of the time. |
This category is populated by pages and templates that use {{ISBN}} and {{ISBNT}}.
In these templates, ISBN parameters are checked for invalid ISBNs as well as extraneous text such as "ISBN", "N/A", "none", dashes (use hyphens instead), lower-case "x" (use "X" instead), and tab characters.
Error messages for erroneous ISBNs look like one of:
- Check
|isbn=value - Invalid ISBN
- Parameter error in {{isbn}}: Invalid ISBN
